She said that the man was mentally ill and that he was not armed, the chief said.
As that officer confronted the man behind a local restaurant, the man “concealed his hand in his pants pocket,” Chief Davis said, and refused to comply, leading the officer to draw a gun.
The police confirmed the man’s death in a statement but did not release his name.
The statement said the officers involved had been placed on administrative leave, which is standard policy after such encounters.
The shooting in El Cajon, a city of more than 100,000 about 15 miles from San Diego, came after recent fatal police shootings of black men in Tulsa, Okla., and Charlotte, N.C., that heightened tensions across the nation.
